This is the '''list of overworld glitches in [[Generation IV]] games'''.

==Pokémon Diamond, Pearl, Platinum, HeartGold, and SoulSilver==
===Graphics corruption===
Standing in certain places of areas such as the [[Great Marsh]], [[Ribbon Syndicate]], or the [[Fight Area]] in {{game|Platinum}}, or {{rt|31|Johto}} in {{game|HeartGold and SoulSilver|s}} may cause the foliage or walls to bend and merge into other graphics near them.

===Intro cutscene oversight===
{{main|Game intro#Generation IV|Game intro → Generation IV}}

In all the [[Generation IV]] core series games, the game overworld seen in the [[game intro|intro]] cutscenes has several differences from actual gameplay. This includes the design of some places and buildings. Similarly, several non-player characters are only found in the intro cutscenes and not in actual gameplay, while other non-player characters are absent or located elsewhere in the intro cutscenes.

For instance, the [[Moss Rock]] is absent from [[Eterna Forest]] in the intro cutscenes of Pokémon Platinum, and the Barrier Station (the house in the way to the [[Bell Tower]]) is missing the sign at the front and has a red color scheme in the intro cutscenes of Pokémon HeartGold and SoulSilver. See also [[Game intro#Generation IV|more examples]].

===Waterfall oversight===
If, before going down on a Waterfall, left or right is pressed on the D pad just before down is also pressed, the player will descend the Waterfall facing left or right instead of down.

==Pokémon Diamond and Pearl==
===Barry Underground glitch===
If the player goes to the [[Underground]] while {{ga|Barry}} is not present at the [[Fight Area]] on Saturday after saving on Friday night on the spot where he would appear, then comes up, the player will be on top of Barry.<!--opponent rather than Barry?-->
If the player saves the game whilst on top of Barry, as the game begins to save Barry's sprite will be brought forward and will stand on top of the player's.

===Barry rematch oversight===
Although Barry appears in [[Fight Area]] only during Saturday and Sunday, if the player stays there without loading a different area or a building, Barry will remain in Fight Area and can be fought even if it's weekday.

===Broken escalator oversight===
This is one of two glitches in the games to be officially acknowledged by [[Nintendo]],<ref>[http://www.nintendo.co.jp/ds/adpj/info/ ポケットモンスター ダイヤモンド・パール／お知らせ]</ref> with the other being the [[surf glitch]]. In early copies of the Japanese versions, after entering the [[Union Room]] on the second floor of the {{si|Pokémon League}} building, which shares the layout with the second floor of any regular [[Pokémon Center]], the player will end up in a wall and not be able to return.

In the case the player has not [[save]]d the game while trapped, it is possible to work around the bug:<ref>[http://www.nintendo.co.jp/ds/adpj/info/how_to_recover.html ポケットモンスター ダイヤモンド・パール／お知らせ（レポート前の場合の修復方法）]</ref>

#Reboot the game to load the previous save file.
#Go to the [[Pokémon Super Contest|Super Contest Hall]] in [[Hearthome City]].
#Speak to the leftmost attendant (there is no need to actually participate in a Super Contest).
#Save the game and restart.

Just like the surf glitch, in case the player saves the game after exploiting this bug, the effect could be corrected with a patch released by Nintendo (including versions for the Nintendo DS<ref>[https://web.archive.org/web/20121128075443/http://www.nintendo.co.jp/ds/adaj/info/recovery_program.html 壁の中でレポートをしてしまったときは（修復プログラムの利用方法] - NDS version</ref> and 3DS<ref>[https://web.archive.org/web/20130719201217/http://www.nintendo.co.jp/ds/adaj/info/recovery_program.html 壁の中でレポートをしてしまったときは（修復プログラムの利用方法] - 3DS version</ref>), which allowed the player to resume the game in front of their house in [[Twinleaf Town]]. Alternatively, the players could mail their cartridges to Nintendo for repair. Both the patches and the repair service by mail were discontinued in February 2018.

===Dress-up Hiker glitch===
When talking to the {{tc|Hiker}} at [[Jubilife TV]] who allows {{OBP|Pokémon|species}} to be dressed up, if a button on the D-pad is pressed so that the player is facing away from the Hiker just before the screen to select which Pokémon will be dressed up opens, the player will not walk on the set path; this can lead to walking through walls or the Hiker, or canceling the action altogether.

===Pal Park Retire glitch===
{{main|Pal Park Retire glitch}}

===Poké Mart text glitch===
This occurs whenever the player uses {{m|Sweet Scent}} or [[Honey]] in a [[Poké Mart]]. Talking to the clerk and selecting the "BUY" menu will yield blank text for the names or descriptions for any of the [[item]]s in stock. Accessing the "SELL" menu will correct the glitch.

{{YouTubeEmbed|LeZvMwBRvM4|channel/UCfA2k3vubAAytJIarM7G2zQ|name= Pokemon Glitches for Bulbapedia |diamond}}

===Silent Route 214 glitch===
If the player goes onto [[Spring Path]] off {{rt|214|Sinnoh}}, the music changes. If you open up your start menu and select any option that opens a secondary menu (Pokédex, Bag, Pokémon menu, etc), close the menu, return to Route 214, there will be no music. Sound effects such as collision sounds still occur and encountering a [[wild Pokémon]] will still play ''[[Pokémon Diamond & Pokémon Pearl: Super Music Collection|Battle! (Wild Pokémon)]]'' as expected. The same glitch can also be activated by changing the music using the [[bicycle]].

===Sticky Hold/Suction Cups bug===
Even if the player's first party Pokémon has {{a|Sticky Hold}} or {{a|Suction Cups}}, the probability of bites while [[fishing]] is not doubled as it was intended to be. This occurs because the equals sign in <code>prob*=2</code> was missed during coding.<ref>[https://twitter.com/im_a_blisy/status/1266504362085552134 Tweet from @im_a_blisy on May 30, 2020]</ref> This was fixed in Platinum.

===Surf glitch===
{{main|Surf glitch}}

==Pokémon Platinum==
===Battle Hall battle transition graphical bug===
After the screen transitions to black upon initiating a regular battle in the Battle Hall, a string of pixels can occasionally appear before the screen fades to white, exposing the overworld form under the black transition.

===Black Belt speech error===
{{GlitchResearch|Is this exclusive to the English versions?}}
Due to consecutive spaces, {{tc|Black Belt}} Eddie in [[Sinnoh]]'s {{si|Victory Road}} will say "Done in" with every letter on an alternating line.

===Full party framerate glitch===
In [[Hearthome City]] and certain other graphics-heavy areas, framerate lag issues have been known to occur when running or riding the [[Bicycle]]. This is most likely to occur when the player has a full party of six Pokémon on them. The fewer Pokémon there are in the party, the less likely the lag issues are to occur.

===Route 227 Underground glitch===
Going to the [[Underground]] on {{rt|227|Sinnoh}} between {{rt|226|Sinnoh}} and the horizontal row with the first patch of [[tall grass]], then coming back up will cause the player to be partly in the ground. Leaving this area causes the player to return to normal.

==Pokémon Diamond, Pearl, and Platinum==
===Cheryl overworld glitch===
At the entrance of the [[Eterna Forest]], sometimes a [[non-player character]] will walk on top of [[Cheryl]].

{{YouTubeEmbed|9SgUwIpm-QU|randomyoshi|HP}}

===Explorer Kit oversights===
{{GlitchResearch|Other places?}}
There are certain tiles where the player cannot use Explorer Kit despite being able to use in the rest of the area, with the message "Rowan's words echoed... <Player>! There's a time and place for everything! But not now." appearing instead.

* Tile south-east of the sign in [[Valley Windworks]]
* In [[Pokémon Platinum|Platinum]] only, two tiles right to the Bug Catcher at the western entrance of [[Eterna City]]
* Outside of [[Jubilife TV]]

===Pal Park manipulation===
{{main|Pal Park#Manipulation}}
This allows the player to migrate any number of Pokémon via [[Pal Park]] by overcoming the "six {{OBP|Pokémon|species}} per 24 hours" restriction.

===Underground item duplication glitch===
This glitch occurs in the [[Underground]] and makes it possible to "clone" a Goods item between two players. There is a chance of losing the item if both players do not follow directions properly.

To clone a goods item, one player must always give the item, and the other must always receive. This cloning glitch can be repeated indefinitely. To clone, one player must give the other an item. The player who gave the item turns the game off without saving, but the receiver should save the game. If the cloning was successful, both players should have the item. However, there is a chance that the cloning will not work and the item will be lost.

Another variation on this glitch can be used to "clone" traps. By having one player place a trap(s) and having the other player pick up the traps and saving, if the first player resets his game without saving both players will have the trap(s).

==Pokémon HeartGold and SoulSilver==
===Additional Boulder error===
In the Japanese versions, a boulder in the [[Slowpoke Well]] can be {{m|Strength|pushed}} off land into [[Water tile|water]]. The boulder will still act as if it was on dry land. It was removed in the localizations.

===Cianwood Gym walking Pokémon glitch===
In [[Cianwood Gym]], if the player stands in the center of the Gym behind the waterfall with a large Pokémon at the front of their party so that they have no [[walking Pokémon]], then changes their lead Pokémon to a Pokémon that can walk inside the Gym, it will appear as a walking Pokémon on the next tier down. After moving a few steps away from the waterfall, the Pokémon is automatically jumped up onto the same tier as the player.

===Floating walking Pokémon glitch===
The player must have a [[Walking Pokémon|Pokémon following them around]] and it must be {{status|poison}}ed. If the Pokémon walks off a [[ledge]] at the same time as it survives the poisoning, then the Pokémon will end up levitating in the air as if it is still jumping off of a ledge. The Pokémon will continue to levitate in the air until the player chooses to jump off another ledge, go into a building, get on the [[bicycle]], or use either {{m|Surf}} or {{m|Fly}}. If the player switches walking Pokémon, the Pokémon will still be seen floating until the player exits the [[party]] menu.

{{YouTubeEmbed|tO3u7uph8ro|tayover18|poison}}

===GB Sounds muting glitch===
If the player turns on the [[GB Sounds]] while {{m|surf}}ing on {{rt|20|Kanto}}, then turns the GB Sounds off while still surfing in the [[Water tile|water]] of either [[Cinnabar Island]] or Route 20, the music will be muted until it is changed.

This glitch will not work if the player encounters a [[wild Pokémon]] while the GB Sounds is active.

{{YouTubeEmbed|ObhQQYe8UI8|TeamFail95|heartgold|soulsilver}}

===Haircut brothers glitch===
If the player tries to get another haircut on the same day from the [[Haircut brothers]] by changing the clock of the handheld, exiting the [[Goldenrod Tunnel]], and entering it again will cause the other brother to be present but he will treat the player as if their {{OBP|Pokémon|species}} have already been given a haircut. Once the day properly changes, the other brother will be present but not give the player's Pokémon a haircut, acting like the player has already gotten one.

===Indigo Plateau guard glitch===
If the player attempts to enter the [[GS Cup]] in the [[Indigo Plateau]] Wireless Club and checks the list of special {{OBP|Pokémon|species}}, the guard blocking the entrance to [[Will]]'s room will not move until the player reenters the building.

{{YouTubeEmbed|Yu_zz23aabY|ChickasaurusGL|heartgold|soulsilver}}

===Invisible grass oversight===
Three tiles on {{rt|44|Johto}} and four tiles in the Swamp area of the {{safari|Johto}} appear to be empty but when the player or the [[walking Pokémon]] is standing on the tiles, [[tall grass]] will appear underfoot. This grass appears between the top of the grass and the [[Water tile|water]] on Route 44, and between the rightmost lake and the grass in the Safari Zone. [[Wild Pokémon]] may be encountered in this grass and Safari Zone objects may not be placed on it.

===Overworld sprite corruption===
Sometimes, when escaping the [[Ecruteak Gym]] is forced by [[Morty]] being absent, the overworld sprites will be corrupted once the {{player}} gets out of the Gym.

===Poké Mart sign position glitch===
Sometimes Poké Mart signs will appear as though they were built on the roots of trees; there is no known way to try getting this glitch to forcefully occur.

===Rock tile behavior oversight===
The upper boulder on a column of two next to the lake in the [[Johto Route 45|Route 45]] side of [[Dark Cave]] functions like a water tile and can be surfed on.

===Walking Pokémon position glitch===
If the [[menu]] is opened while the [[walking Pokémon]] jumps off a [[ledge]] and the player checks the status screen of any {{OBP|Pokémon|species}} in the [[party]], the Pokémon will get a bit higher up, so viewing the stats of a Pokémon continuously will result in the Pokémon going off-screen.

==Pokémon Platinum, HeartGold, and SoulSilver==
===Wi-Fi Plaza glitch===
If the player goes to the [[Wi-Fi Plaza]], runs in the direction of another player, and reaches them about a second before they warp out, the two players will merge into each other until the second one warps out.
